The former World No. 15 was the last active American man to have reached a major semifinal before he announced his retirement. He did that in 2005, a year that also saw him win a career-high 37 match wins. At the 2005 U.S. Open Ginepri won three consecutive five-setters before bowing out to Andre Agassi in a five-set thriller in the semis. During his career, the Kennesaw, Ga. resident reached the fourth round or better at all four Grand Slams and represented the U.S. in Davis Cup (2004 and 2009) and in the Olympics (2008).

“Although every athlete knows this day will eventually come, it doesn't make the decision to retire any easier,” said Ginepri. “To play tennis as a profession and compete on the biggest stages around the world is a privilege, and I will forever be grateful to have had the opportunity.”

According to his agency, Octagon, 32-year-old Ginepri will continue to stay involved with the game through the Ginepri Performance Tennis Academy, located at the Olde Towne Athletic Club in Marietta, Ga. The academy strives to develop juniors into potential collegiate student athletes and stresses leadership skills of hard work, perseverance, attention to detail, compassion for others, and lasting relationships.
